Change Network settings

Configuration
1

Hi,
due to a technical problem with my FritzBox, I recently had to reset my (second) WLAN in which my HomeAssistant was also connected. Now the Pi on which it is running is unfortunately no longer accessible in the network (neither via LAN nor WLAN, via LAN it should normally always be accessible or at least have an IP address in the FritzBox interface or not?)
Is there a way to change the network settings by accessing the PI directly (screen)? Or does anyone have another idea how I could solve the problem?

Many thanks in advance!

If you connect directly to the PI with a monitor/keyboard, you should be greeted with the HA Welcome screen. It should show you the current IP address assigned.

Okey thank you, I‘ll try it.
If haos doesn’t get an ip-adress, can I also change the network settings there by command?

HA should get an IP address if your network is configured properly and DHCP is allocating addresses. Or if you have assigned a static IP address.

You can change network settings in HAOS.

ha net ?

login
network update eth0 --ipv4-method auto

Just head over to Supervisor > System > Host > Change. You can tweak your IP settings and DNS from there and restart.

The first post indicated that the system can’t be accessed via a web browser.

I’ve now fixed the problem.
Connecting the screen and reconnecting to the network via cmd was the way to go.
HAos started normally but was actually no longer able to establish a connection to the network.

Thank you all for your help!
Have a nice weekend, you have made mine much less stressful :smile:
